目的：进一步推进我军弹药维修工作，完善弹药表面除锈工艺。方法综合分析多种除锈方法，确定弹药表面除锈新作业方式，确定弹药表面喷砂除锈应使用的磨料类型和喷枪倾角，以85加弹丸除锈为例，对喷砂除锈时弹药基体温度进行理论计算和试验测量，对比分析内装含能材料的热感度确定安全性。结果温度最大理论升值为6.35益，试验测量平均值为3.72益，远低于内装含能材料热感度。结论利用喷砂技术进行弹药表面除锈可确保作业安全，有效提高作业效率。
Objective To further promote ammunition repairing in Chinese army, and to improve the technique of rust removal from ammunition surface. Methods Several rust removal methods were comprehensively analyzed, the new operation method using sand-blasting for rust removal from ammunition surface was proposed. The abrasive type and the obliquity of spray gun for rust re-moval from ammunition surface by sand-blasting were determined. Using the rust removal of 85 plus projectile as an example, theo-retical calculation and experimental measurement were conducted for the ammunition substrate temperature during rust removal by sand-blasting, and the safety was assured by comparative analysis of the thermal sensitivity of the energetic materials. Results The maximum theoretical temperature increase was 6. 35℃ and the average experimental measurement was 3. 72℃, which was far low-er than the thermal sensitivity of the energetic materials. Conclusion Rust removal from ammunition surface using the sand-blasting technology could ensure the operation safety and effectively improve the operation efficiency.
